Crane rotation speed?
Hi!
We have a crane/dolly being built by local engineering students as a semester assignment. They ask us about maximum rotation speed of the crane head. We don't know really. Can anyone help? Thanks! |

Hi Jiri.............
You might get some usefull info here:
Pan & Tilt Rigs The fastest (of those that bothered to list it - an awefull lot don't) was 210 degrees per second. That's one serious whip pan. Others I found were 90, 90, 45, 15 & 9 degress per second. Personally, I'd say 120 degrees per second would be as fast as you'd ever realistically want to go, that's a full circle in 3 seconds, enough to make you throw up your breakfast. CS |

Hello Jiri,
I would not mind the speed this much as in 120 degrees a second is already fast enough for most shots. I would be more worried of the fast starts and stops of both the rotation as well as the vertical movement. an acceleration and deceleration can be about 6 m/s 2....
